		<p>
			When working with nested droppables &#8212; for example, you may have
			an editable directory structure displayed as a tree, with folder and
			document nodes &#8212; the
			<code>greedy</code>
			option set to true prevents event propagation when a draggable is
			dropped on a child node (droppable).
